This is what I am experiencing.

I fire up IE6 tab. Change my js code.  Hit refresh complete (no cache) I expect it to see my change, it does not. If I click "Internet Explorer Options" nothing happens.

If I fire up IE8 (the default IE on this Winxp SP3 system) and clear cache, then all tabs respond as I would expect, showing my change.

The clear cache is the one essential piece to this product. I know that IE is a bear, but taming this piece would make it worth buying.
